Diagnosis

Irura shendurney sp. nov. is similar to I. bidenticulata Guo, Zhang & Zhu, 2011 , but can be distinguished by the relatively longer embolus arising at 9 o’clock position (vs 11 o’clock position); conical RTA in retrolateral view (vs subquadrate) and relatively shorter retrolateral cymbial process (vs curved and longer) (cf. Figs 39–45 ; Guo et al. 2011: figs 8–10; Logunov 2022: figs 7–8). The new species is also similar to I. uniprocessa Mi & Wang, 2016 , but can be distinguished by the presence of palpal tibia with membraneous RTA (vs palpal tibia without distinct apophysis); basal cymbial process broad and triangular, directed ventrad in retrolateral view (vs narrow and finger-like directed dorsally) (cf. Figs39– 45 ; Mi & Wang 2016: figs 1c–e, 2a–b).

Etymology

The specific epithet refers to the Shendurney Wildlife Sanctuary from where the species was collected.
